My invention i'elates to registering devices for printers use with which printing plates may be held in registered position. Specifically my invention relates to improvements in registering devices of the type disclosed in the \Varnock Patent $21,007,164. p

In the VRIIIOCk registering device as disclosed in'the aforenoted patent, a carrier is provided which has a worm gear driven by a worm mounted in vertical position within the carrier. The worm has rotatably -mounted I 'thereina clamping jaw. Extending down the axis of the clamping jaw is an aperture for the insertion of a key which fitswithin a key socket in the worm, so that by inserting the kevy and turning it, the worm maybe rotated. Mounted in an assembly coaxially with the worm gear are two toothed gears,'

one on each side of the worm gear, which gears engage the teeth of toothedtrack sec-- tions mounted on each side of a medial groove in the foundation plate. In the foundation plate having a groove between the toothed track sections ink runs down the walls of the *groove and becomes smudged in the teeth of v the rack where it hardens. Then there isno easy way to remove the hardened ink except.

by soaking the foundation plate. \Vith. the I teeth of the rack covered with hardened ink litthe registering device becomes practically in- V operable. V

It is the object of my invention to provide a registering device operable on at similar principle as that disclosed in the 'atorenoted FlVarnock patent which shall have a single toothed track section extending medially down the center of each groove in the tonndation plate. Thus, slots will be formed on each side of the toothed track, which slots 1 therein. It is also my Object to provide gear to engage the toothed track-which will have an axle bearing which will firmly jour nal the gear instead of having bearing por tions provided in the periphery of the worm fl lie above gandiother objects which the anufacture =;of y a stronger: registering device with. fewer component parts and; to r whi'cli reference will beimadein r the ensuing; djsclosure,'I'accomplish byotha t certainicom bination and arrangement ojff pants of i llCb: Ihaveshown preferred embodiment-Q .1

This member I flattened portions at the ends which engage has pinion gear teeth 10 cut in its outer periphery, and subsequently worm gear driving portions 11 cut medially therein.

In the manufacture of the'gear'itis'entirely optional which type of teeth are cut first in the pinion. The unitary member is mounted on the axle or journal 9, theaxle I being rounded medially and only having the walls 6a ofthe carriage frame. a

The carriage frame has a recessed portion 13 having a flange 14: which provides a'thrust bearing for the peripheral flange 15 of the neck of the jaw member. Thejaw member ally mounted pinion within said housing,

meansfor driving said pinion, afoundation platehaving lslots: therein, with toothed tracks mounted medially Within said slots,

I ink slots'at' the sides of the tracks, said hous-.

ing havingdownwardly extending members extending within said ink slots.

' EMIL E. THIELJ has a clamping portion 16, which, in use, '7

bears against'a printing plate mounted on the foundation plate which is to be held in register'ed position thereon. Extending through a the axis of the jaw member is an aperture. 12 through which a key 17 may be inserted to engage a key socket l8 inthe upper end ;of the worm 19. The frame has extensions 20 which-extend into the ink slotsduring the printing plate has been positioned properly, a

movement of the registering device. The

extensions provide a support. and prevent the rocking of the registering device under tension. The extensionsalsotend to wipe 'out the slots. i

' The rotation of theworm by engagement' with theworm gear portions '11 of the 'integral members rotates the pinion 10 which engages the teeth of the track 3. When the several of the registering devices "similar to the one described herein, located in different positions and in 'dilferent grooves, firmly hold the printingplate inplace.

As has beennoted, the unitarypinionyand worm gear member-provldes a much stronger drive than in theaforenoted Warno'ck patent, in which pinionsand azworm gear are mounted on' an unjournaled shaft. Further, the ink slots prevent thetrack from becoming clogged up with hardene d ink, be-' cause theengageinent of the gear with the teeth of the track causes the ink to be 50,

squeezedoutwardly into the slots. While I have shown my novelregistry de-: vice as an improvement particularly on the Warnock device, it is thought 'to be within the realms of mechanical equivalencyto construct other types of devices 'witha combina-' tion worm drive and pinion, with the ink grooves at the sides of the rack-member,

which I consider to be the essence of my invention. Q Having thus; described my invention, what I claim as new and desire to secure by Letters 7 Patent, is
